Thanks to OpenModel for sponsoring this project! OpenModel offers client-specific discounts of up to 90% for Codex and 60% for Claude Code across supported models, helping developers cut API costs without changing how they work. Just connect your OpenModel API key and keep using Codex or Claude Code as usual — supported clients are detected automatically and discounted routes are applied with no extra parameters or manual routing required. You can also configure fallback behavior per API key, choosing whether to continue at standard pricing or stop when a discounted route is temporarily unavailable. DeepChat users can register via this link. |

DeepChat is a powerful open-source, local-first AI agent desktop client that brings together models, tools, Skills, agent runtimes, Tape, and long-running sessions in one desktop app. Whether you're using cloud APIs like OpenAI, Gemini, Anthropic, or locally deployed Ollama models, DeepChat delivers a smooth user experience.
DeepChat's sessions and agent processes follow the Tape.systems philosophy: keep the process, so context, tool calls, requests, and results stay recoverable, traceable, and inspectable. It also provides strong MCP support, installable Skills, ACP agent integration, and remote control for Telegram, Feishu/Lark, QQBot, Discord, WeChat iLink, and other messaging workflows.

DeepChat's session Tape follows the Tape.systems philosophy and keeps agent work recoverable and inspectable. Trace previews expose request sequences, provider/model metadata, Tape view manifests, included or excluded entries, and token budgets, making long-running agent sessions easier to debug and resume.
DeepChat Skills are designed to be compatible with the standard Agent Skills specification. A Skill can include task instructions, reference files, assets, and optional scripts, so DeepChat can act more like a domain specialist after it is enabled.
You can install Skills from folders, ZIP files, or URLs, and import/export them with Claude Code, Codex, Cursor, Windsurf, GitHub Copilot, Kiro, Antigravity, OpenCode, Goose, Kilo Code, and other compatible tools.
Built-in Skills cover algorithmic art, code review, DeepChat CLI, DeepChat settings, document collaboration, DOCX, frontend design, git commit messages, infographic syntax, MCP building, memory management, PDF, PPTX, Skill creation, and XLSX workflows.
Quick start:
- Open Settings → Skills
- Install or import a Skill
- Enable it in conversations that need that capability
DeepChat has built-in support for Agent Client Protocol (ACP), allowing you to integrate external agent runtimes into DeepChat with a native UI. Once enabled, ACP agents appear as first-class entries in the model selector, so you can use coding agents and task agents directly inside DeepChat.
Quick start:
- Open Settings → ACP Agents and enable ACP
- Enable a built-in ACP agent or add a custom ACP-compatible command
- Select the ACP agent in the model selector to start an agent session
To explore the ecosystem of compatible agents and clients, see: https://agentclientprotocol.com/overview/clients
DeepChat can be controlled from messaging apps, so you can keep a session running even when you are away from the desktop. Configure remote channels under Settings → Remote.
Supported channels include Telegram, Feishu/Lark, QQBot, Discord, and WeChat iLink. Remote endpoints can bind to one DeepChat session, then create new sessions, list and switch recent sessions, stop generation, open the current session on desktop, answer pending questions or permission prompts, switch models, and check runtime status.
Common commands include /start, /help, /pair, /new, /sessions, /use, /stop, /open, /pending, /model, and /status.
Any service that speaks the OpenAI, Gemini, or Anthropic API format can be added as a custom provider next to the built-in ones.
DeepChat is suitable for various AI application scenarios:
- Daily Assistant: Answering questions, providing suggestions, assisting with writing and creation
- Development Aid: Code generation, debugging, technical problem solving
- Learning Tool: Concept explanation, knowledge exploration, learning guidance
- Content Creation: Copywriting, creative inspiration, content optimization
- Data Analysis: Data interpretation, chart generation, report writing
